最近研究表明,12导联心电图QT间期变异反映心肌复极变异,QT间期离散度增加可能是室性心动过速的电生理基础[1]。肥厚性心肌病室性心律失常多见,本文旨在探讨肥厚性心肌病患者QTC间期离散度(QTcd)变化。1 资料和方法1.1 对象 肥厚性心肌病组:1985年～1995年住院的肥厚性心肌
Recent studies have shown that 12-lead ECG QT interval variation reflects myocardial repolarization variation, QT interval dispersion may be the electrophysiological basis of ventricular tachycardia [1]. Hypertrophic cardiomyopathy ventricular arrhythmias more common, this article aims to investigate the QTC interval dispersion (QTcd) changes in patients with hypertrophic cardiomyopathy. 1 Materials and Methods 1.1 The object hypertrophic cardiomyopathy group: 1985 ~ 1995 hospitalized hypertrophic myocardium
